We performed humeral head replacement 8months after the index surgery; histological examination of the collapsed area revealed necrosis, degeneration, fibrillation, and granulation in the cartilage and trabeculae. Osteonecrosis due to the use of metal anchors was considered the primary cause of the post-operative humeral head collapse. As the demand for arthroscopic cuff repair is expected to increase in the future, we recommend that surgeons become aware of the potential for complications, as seen in the present case.
